I'm a new user of CMAP and I have a problem when I input data. For
me, when I'm using Buil-in view() to get data I cann't put
expression for what data I need and the problems are I confused
these inputs. Besides, with Buil-in getnum()I can do that but I
cann't input data for matrices. Do we have other functions look like
view() and getnum()which I can put my expressions and can do well
with matries ?
